Safety concerns
There is evidence that using some ayurvedic medicine, especially those involving herbs, metals, minerals, or other materials involves potentially serious risks, including toxicity.[16][2][17]
A research study published in the Journal of the American Medical Association[18] found significant levels of toxic heavy metals such as lead, mercury and arsenic in 20% of Ayurvedic preparations that were made in South Asia for sale in America. The Journal found that, if taken according to the manufacturers' instructions, this 20% of remedies "could result in heavy metal intakes above published regulatory standards"[18] Similar studies have been performed in India, and have confirmed these results. In response to the study, some practitioners of Ayurveda claimed that "heavy metals are integral to some formulations and have been used for centuries. There is no point of doing trials as they have been used safely and have mention in our ancient texts."[19]
